What is a Weighted Blanket?

Generally, a weighted blanket is often referred to as a heavy blanket, an alternative name. But, what is a weighted blanket? 

What is a weighted blanket?

A weighted blanket is like any other normal blanket, composed of different colors, fabrics, and size. However, there is something that makes it different from the normal blankets. What is that?

The filling of heavy blankets includes glass beads, plastic pellets, beads, discs, or flaxseeds. Mostly, these materials are mixed with lighter materials for producing weighted blankets.

The secret behind weighted blankets and their usage is that they gently apply pressure to your body while laying on a bed, reducing stress and anxiety for most people.

What is the purpose of a weighted blanket?

It is highly recommended to use a weighted blanket for anxiety and other similar health issues. Additionally, studies claim that sleeping with a weighted blanket enhances sleep efficiency and helps you deal with sleep disorders.

Here are some disorders that weighted blankets are the perfect solution for:

  • PTSD
  • Anxiety
  • Insomnia
  • ADHD
  • Restless leg syndrome
  • Depression
  • Autism

Also, there is not any risk of sleeping with a weighted blanket in pregnancy. You are allowed to do so, and the only problem that it may bring is the additional heat coming from the weight of a heavy blanket.


If we go back to 1999, it can be taken as a year of the first implementation of weighted blankets. At that time, Tina Champagne, therapist, started using weighted blankets for helping mental-health patients.

However, as an official inventor and designer of weighted blankets is considered Keith Zivalich. Zivalich invented the weighted blanket in 1997. Due to their deep pressure stimulation, weighted blankets became broadly popular around the world.
They help your body release calming hormones, like dopamine and serotonin, which enhance your motivation, impulse control, attention, memory, social behavior, and sleep.

Weighted Blanket For Kids

When you choose a perfect weighted blanket for kids, it is recommended to choose the one with the weight (size) equal to 10 percent of your body weight, and you can add up one or two pounds. Choosing the weighted blanket for a toddler that will fit it best is important because you have to ensure that your children benefits greatly.

How to know which heavy blanket is the best for your child? Let’s look at the list below, which shows the recommended children’s weighted blanket according to their weights:

  • 20 lb = 3–4 lb blanket
  • 30 lb = 4–5 lb blanket
  • 40 lb = 5–6 lb blanket
  • 50 lb = 6–7 lb blanket
  • 60 lb = 7–8 lb blanket
  • 70 lb = 8–9 lb blanket
  • 80 lb = 9–10 lb blanket

Weighted blankets should not be used for babies. Therefore, if you have a five-year-old child or even younger, talk to a doctor before using it.

How to Choose a Weighted Blanket – Formula

To choose a weighted blanket for you, you need to calculate its weight. Then, when you know the blanket’s weight, you can easily figure out and choose what’s best for you. 

When calculating the weight of a blanket, you need to divide your current weight by 10 and add one or two pounds to the product. 

Note: Our Weighted Blanket Calculator instead adds 1.5 lb to the product in the formula calculation. However, if you want an instant weighted blanket calculation, use our calculator.

Whether you want to calculate the blanket’s weight for a single person or a couple, we can provide two different formulas.

Calculation for a Single Person

In pounds:

\text{Weight = (your weight / 10) + 1.5}

In kilograms:

\text{Weight = (your weight / 10) + 0.68}

Calculation for a Couple

If two people have the same weight, you can use only one weighted blanket for both of them. However, if their weights differ significantly, you can use another formula to calculate the proper weight of a blanket needed.

To find the weighted blanket’s weight, take 7.5% of their combined weight.

\text{Weight = 0.075} \times \text{couple's combined weight}
